Sorry it doesn't work for me.

 Code:
? "createobject kixforms: "
$kixforms = CreateObject("Kixtart.Form")
? "show form:"
$kixforms.visible = 1
@error " " @result " " @serror ?

gives

 Code:
createobject kixforms:

 Code:
? "createobject kixforms: "
$kixforms = CreateObject("Kixtart.Form")
? "show form:"
$kixforms.show()
@error " " @result " " @serror ?

gives
